you can check prices for h&r and stock porsche row springs, pick the cheapest.
Leading evidence: 'Check prices' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check prices' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt.

The B8's are shorter but the B6's supposed to be ok to use with a "sport spring".
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I went with the H&R sport springs with Bilstein B8 struts/shocks (dampers), Tarret monoball front top mounts (rear top mounts are stock), and H&R sport sways (3 way adjustable - 25 mm front 24 mm rear). I can't comment on the others as I haven't compared them. All I can is is that my experience from stock is night and day. While the car is certainly much "stiffer" than it was, it's not "harsh" by any means (it's actually much less rattly than it was before as my front top mounts were shot). The handling is incredible - and I didn't think it was bad before the changeover. Good luck
I have the 2002 C4S. The best, IMO, is the Porsche X74 lowering kit. Designed specifically by Porsche for the C4S, it comes with the lowering shock and springs, PLUS the appropriate engine and transmission mounts to maintain the correct alignment between the engine/transmission/axles to the lowered height. None of the aftermarket ones come with the correct engine mounts.
If all you want is the lowered look and do not plan on tracking the car, then any of the aftermarket ones, like Eibach, Bilsteins, H&R, etc, should do. The axle u-joints won't be stressed with street driving and can handle the misalignment.
If you do plan to track the car, then add GT3 front lower A arms and adjustable anti-sway bars to your budget. With the correct wheel alignment and negative camber, you'll love the track performance combination of these with the Porsche X74 suspension. I do.
BTW, don't confuse the X74 with the X75. The X75 is for the twin turbo, with slight difference to allow for the heavier weight of the turbo.
Really? Did your dealer tell you ^this^? While I suppose it justifies your $ outlay, it's not very accurate. Axle U joints? You mean CV joints don't you? Most of the "sport springs" don't lower the car more than an inch - this won't "stress" your CV joints...
"PLUS the appropriate engine and transmission mounts to maintain the correct alignment between the engine/transmission/axles to the lowered height. None of the aftermarket ones come with the correct engine mounts."
Wow... that's a new one... I love the internet
My Techart springs have the Techart number and the word Eibach printed on them so not sure about that "get what you pay for" thing when choosing between these two brands. Appears both are made by Eibach.
Take a look at the link below - as others have mentioned H&R with the b6s is a very popular choice - let us know if you have any questions!

Eibach manufacturers Techart springs, but it is to Techart specs.
Bilsten manufacturers thier shocks and struts.
I'm not sure who does thier sway bars, my guess is Eibach.
LOL. Take a breath, dporto. As I said, it's "IMO", aka "In My Opinion". And you have yours. Opinions are like ********, everyone has one. But, it's a little different from being one. ROFL!!
The Turbo kit is x73, not x75.
Also, I don't believe the X74 kit was for the wide body cars, I believe the C4S also took the X73 kit.
In regards to the engine mounts, these are just stiffer, no alignment changes.
Another vote for H&R and Bilstein B6. First changed out the shocks, as the originals were toast, then after going to stock size 17" wheels hated the SUV look, so wound up doing the whole thing over again! I am getting too old for this stuff, will be 62 in three weeks and feeling it.
A bit of a different question, I can not go with new springs that lower the car due to my driveway slope into garage (would bottom out in front (or hit pipes backing in). Is there a good upgrade that would leave my car at stock height?
Your statements weren't presented as opinions, they were stated as facts - and they are clearly nothing more than bs. As is your smarmy reply. Now go play with your perfectly aligned engine/transmission combo and axle U joints.. 😉
Try stiffer shocks and bigger sway bars. That's what I would like: shorter spring but same spring rate as stock, then stiffen side to side with bigger sways.
^This^ would probably be something like the Bilstein B6 (heavy duty). The B8's are shorter but the B6's supposed to be ok to use with a "sport spring".
